Built on Intel's LGA 2011 socket, this six-core, twelve-thread processor operates at a base clock of 3.20 GHz, boosting up to 3.80 GHz under turbo conditions, which made it ideal for enthusiasts in 2011. Its 12 MB shared L3 cache enhances data access speeds, supporting demanding workloads like 3D rendering and scientific simulations. Launched on November 14, 2011, at a price of $583, the i7-3930K unlocked overclocking potential with its multiplier, appealing to users seeking customizable clock speeds. This architecture emphasized raw power over efficiency, with a 130W TDP that required solid cooling solutions for sustained operation. Performance metrics for the Intel Core i7-3930K reveal its enduring capability in benchmark suites, scoring 6,973 points in Cinebench R23 multicore tests, which highlights its strength in parallel processing tasks. In Geekbench multicore evaluations, it achieves 2,991 points, demonstrating solid throughput for productivity applications. Single-core performance reaches 984 points in Cinebench R23, sufficient for lighter threaded workloads of its era. Older benchmarks like Cinebench R20 multicore at 2,928 points and R15 multicore at 702 points underscore its balanced efficiency across rendering and encoding scenarios. These scores position it as a reliable performer even today for budget retro builds, though modern alternatives surpass it in IPC gains. Competitively, the i7-3930K carved a niche against AMD's Phenom II and early FX series by offering superior per-core efficiency and integrated memory controller support for triple-channel DDR3. It outperformed contemporaries in multi-threaded applications, often edging out the i7-3960X in value-driven scenarios due to its lower launch price. Against Intel's own lineup, it bridged the gap between mainstream and extreme editions, providing near-Xeon level threading without enterprise premiums. In 2011's landscape, its turbo boost and Hyper-Threading gave it an edge in content creation over quad-core rivals. Today, it serves as a benchmark for vintage comparisons, holding up in legacy software but yielding to newer architectures in power-normalized tests. For optimal pairing, the i7-3930K thrives with X79 chipset motherboards like the ASUS Rampage IV or Gigabyte GA-X79-UD3, enabling full utilization of its unlocked multiplier for overclocking to 4.5 GHz or higher. Pair it with 24-32 GB of DDR3-1600 RAM in triple-channel configuration to maximize bandwidth for memory-intensive tasks. A high-end cooler such as the Noctua NH-D14 is essential to manage its 130W TDP during prolonged loads. Graphics-wise, it complements NVIDIA GTX 900-series cards for gaming rigs or Quadro GPUs for professional workflows. Storage setups benefit from SATA 6Gb/s drives, while a 750W PSU ensures stability in multi-GPU configurations.
